3 Claims.

This invention relates to wall structures of the character described in my co-pending appli-' cation Serial No, 103,154, filed September 29, 1936,- now Patent No. 2,125,136, issued July 26, 1938.

The present invention relates particularly to certain modifications of and improvements in the invention of my above identified co-pending application and to certain cooperating elements for use in connection with my prior structures and modified forms thereof herein shown for meeting certain requirements of interior decoration and finish in the associated room.

One of the principal objects of the present invention is to provide an improved frame for swinging doors, windows, and the like.

Another object is to provide a channel and supporting member and cooperating trim member especially adapted for forming protruding corner wall portions and the like.

Another object is to provide a hanger for curtain rods, pictures and the like arranged for use in connection with the channel supporting member and cooperating trim member and which may be readily installed thereon in such locations as desired.

An equally important and more specific object is to embody the channel and trim member in a base board or wall panel construction in such a manner that the channel and trim member may be provided with electrical plug-in receptacles in such locations as desired with the electric wires accommodated within and protected by the combined channel and trim members.

Other objects and advantages will become more apparent from the following specification wherein reference is made to the drawings in which:

As described in my co-pending application, the supporting channel i is preferably in the form of a single sheet of metal bent or formed between its lateral margins to provide a readily accessible channel base portion 2 and concavo-convex flanges 3 which curve from the lateral margins of the base 2 upwardly and then inwardly toward each other part way of their length, and then curve outwardly from each other part way of the remainder of their length.

In plaster wall structures and the like, it is desirable to provide metal door and window frames, and for this purpose the flanges 3 have free end portions 4 and 5, respectively. The portion 4 extends parallel to the finished wall with which the channel is to be associated a sumcient distance to provide a metal framing of the desired dimension lengthwise of the wall structure. The free end portion 5 of the other flange 3 extends parallel to and in the same plane as the portion 4 part way of the length of the portion 5 and then extends inwardly transversely of the wall, as indicated at 6 in Fig. 1, to form the exposed end of the wall or frame. The portion 6 is preferably arranged so that the angle between the portions 5 and 6, indicated at I, is slightly greater than a right angle, thus providing a slight draft for effecting a more tightly fitting seal with the door or window when the door or window is closed. The margin of the portion 6, farthest from the portion 5, is bent to provide a shoulder 8 which is substantially parallel to the wall surfaces, and therebeyond is bent to extend transversely of the wall and parallel to but offset from the portion 6, as indicated 5 at 9. A remaining portion ill of the metal beyond the portion 9 is bent back parallel to the portions 4 and 5 so as to form a frame at the opposite side of the wall. Thus, for forming the door frame, it is only necessary to provide a small upright support such as the wooden stud secure the channel support thereto by suitable screws l2, then fill between the metal portions 4 and ill with plaster, and strike the plaster off flush with the outer surfaces of the portions 4 and I0. After the wall is thus completed, the trim member l5 may be snapped into place in the supporting channel I.

The trim member |5, in the form illustrated, is the same as that shown and described in my copending application and comprises a single sheet of metal having portions at the lateral margins folded back upon or parallel to the face of the metal part way toward its mid-portion and then outwardly to provide flanges l6 which are concave outwardly and adapted to spring in between and tightly fit within the flanges 3 of the supporting channel I. The door, or swinging window, indicated at ll, is preferably formed of metal but may be of wood or other material. The end of the door I! adjacent the portions 6, 8 and 9 of the frame formed is substantially complementary in contour thereto so that the door may be closed in tight sealing relation to the portions 6, 8 and 9. The other edges of the door may be similarly formed as also may be the complementary portions of the door frame, thus assuring a firm sealing engagement.

If, in some instances, it is desired that the plaster coating approach more closely to the door frame on one side or the other, the structure illustrated in Fig. 6 may be utilized. This structure employs a supporting channel 20 which corresponds in all respects to the-channel above described, with the exception that the portion 2|, corresponding to the portion 4 heretofore described, is bent back generally parallel to and spaced from the adjacent flange 22 and then outwardly to provide a wing portion 23 which is secured to the support or stud 24. Thus the plaster may be struck off entirely to and flush with the outer exposed surfaces of the channel 20, as illustrated.

In some instances, it is necessary to provide walls having projecting corners wherein it is desirable to continue the trim member from a horizontal to a vertical plane. For this purpose a channel 2, such as above described, is disposed horizontally with its flanges 3 extending upwardly, and another channel 2 is placed vertically with its base flush against the end of the horizontal channel 2. The flanges I6 of the trim member |5 are cut away for a short distance from the end which is to form the corner, thus leaving an overhanging base portion, as indicated at 26, which is of sufiicient length to extend from the base of the vertical channel 2 outwardly substantially to the end of the vertically disposed trim member l5 of the vertical channel. Thus, when the trim members are assembled in the horizontal and vertical channels, a substantially continuous surface is formed from the horizontal trim member to the vertical trim member, the ends of the vertical channel being concealed by the end portion 26. The terms horizontal" and vertical as above used are merely for convenience in defining the relation of the parts, as obviously the same manner of forming corners, whether right angular or otherwise, may be utilized merely by allowing an end portion of one trim member to overlie the open end of the other channel 2.

In Figs. 4 and 5, a channel 30, corresponding in general to the channel 2, is mounted for reeeiving a base board trim for the wall. In this form one of the flanges 33 of the channel may have its free end portion disposed vertically to form a portion of the base board of the desired height. The other flange 32 has its free end portion 34 bent back at right angles toward the base of the channel so as to lie flush onthe floor, the free margin of the portion 34 being turned down to provide an anchor lug 35. The trim member 36 may be made more decorative and somewhat thicker fore and aft of the wall than the trim member |5, as illustrated in Fig. 5, and preferably of such thickness that it may accommodate suitable electric plug-in receptacles, as indicated at 31. By providing a number of short lengths of trim 36 with plug-in receptacles installed, it is apparent that the plug-in receptacles may readily be installed in the wall of the room at any location along the channel desired. The electrical power lines 38 may be accommodated within the supporting channel 30 without interfering with the installation of the trim member and the plug-in receptacles may be readily connected thereto in the desired locations. With this arrangement, the receptacles are easily shifted in position when desired and may be readily removed ior servicing and the like while at the same time the electric wires are encased in a fireproof casing.

It is apparent that with the structural elements herein described, various other utility devices may be readily installed at the desired locations on the wall, and in addition to such utility devices as plug-in receptacles, curtain rod hangers, door bumpers, picture hangers and like utility devices may be included in the combination in such a manner that they may be readily removed, replaced or changed as desired. As an example of a utility device such as a curtain rod hanger installed in connection with the channel and trim member of the present invention, reference is to be had to Figs. 7 and 8.

In Figs. 7 and 8 there is illustrated a horizontally extending channel and trim combination with a curtain rod hanger for use in connection therewith. The channel member 40 is secured in the wall in the usual manner and one of the trim members 4| is snapped into place. Next, there is disposed in the channel member a curtain rod hanger 42 having a base portion 43 which is of relatively thin flat metal and, in contour, is substantially complementary to the internal configuration of the channel 40. The outwardlyexposed portion of the rod hanger may be of any desired shape but in the form illustrated is merely a continuation of the flat metal of the base 43. The base of the curtain rod hanger is inserted with its width parallel to the channel 40 and is then turned about its axis so as to fit the base portion 43 snugly within the channel. Thereupon the other trim member 4| is snapped into place. The two trim members 4| then have their adjacent ends abutting opposite faces of the holder 42, thus securing it in place. The holder preferably has portions 44 which are of the same or greater length than the width of the trim members so as to completely fill or conceal the space between the adjacent ends of the trim members 4|.

Referring next to Figs. 9 and 10, there is illustrated a curtain rod holder which is to be installed in vertically extending channel and trim combinations. In this form of the invention, the channels 50 extend vertically and receive the trim members 5| in the usual manner. Short sections of trim member, such as the section 52, are provided at their ends with small notches 53. Secured onto the outer face of the section 52 is a bent metal hanger 54, the ends of which are of the same width as the notches 53. The free ends of the hanger 54 are fltted into the notches 53 and then bent back and around into juxtaposition with the rear face of the trim member 52, as indicated at 55, so that the trim portion 52 with the hanger 54 installed thereon terminates at its ends in straight lines. Wherever a hook or hanger 54 is desired, it is only necessary to insert between the ends of adjacent trim members 5| one of the trim sections 52 with the attached hanger 54.

It is apparent from the foregoing that hangers for pictures and other objects may readily be installed and secured in place in the channel and trim combinations herein described. Furthermore, many fixtures, such as door bumpers and the like on the base board or paneling of the room, may readily be provided without detracting from the utility and applicability of the invention.

Having thus described my invention, I claim:

1. In a wall construction, a channel member having a base portion and relatively overhanging flanges'and secured to the wall with its flanges extending outwardly of the wall for receiving trim members, trim members having resilient portions received between the flanges and resiliently engaging the flanges for securing the trim members to the wall, a utility device having a relatively rigid base received between the flanges in one relatively rotated position of the device and channel member and secured from withdrawal from the channel member outwardly of the wall by .engagement of portions of the base with the flanges of the channel member in another relatively rotated position of the device and channel member, and adjacent ends of the trim members engaging the utility device and constraining it from rotation out of its secured position.

2. In a wall construction, a channel member having a base portion and relatively overhanging flanges and secured to the wall with its flanges extending outwardly of the wall for receiving trim members, trim members having resilient portions received between the flanges and resiliently engaging the flanges for securing the trim members to the wall, a utility device having a base portion received between the flanges and engaging beneath the flanges for connecting the device to the channel member, and the adjacent ends of the trim members engaging the utility device and opposing shiiting of the device from it; connected position.'
